The present invention relates to an improved headlight and supporting means therefor, such as is especially, but not necessarily, adapted for use on present-day automobiles.

More specifically, the invention has to do witha novel lens construction, the latter characterized by a one-piece glass. or equivalent unit, said unit being fashioned to provide a liquid container including an inner flat disc lens and an outer concavo-convex lens, these connected by a 'marginal annular rim. The receptacle thus constructed is charged with a light-diffusing liquid, for instance, water, the latter in conjunction with the two lenses functioning to modify the projected light rays in a, manner to diminish-and l5 minimize objectionable glare.

Another feature of the invention pertains to a metal or equivalent frame, this encasing the rim of said double lens unit, and said frame constituting a light interceptor and shield, whereby to compel the outgoing or projected light rays to pass through the lenses and intervening liquid filter.

scription and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views-- Figure 1 is a view essentially in section, but partly in elevation, showing the complete supporting means andheadlight, with the parts in readiness for use.

Figure 2 is a fragmentary, view of the outer concavo-convex iensillustrating the prismatic projections.

Referring now to the drawing,the supporting means, which is attachable to a suitable part of the automobile (not shown) is denoted, generally speaking, by the numeral 5. It is characterized by a base bracket 8 having a retaining hook I and carrying a bolt and nut supporting a complemental clamping hook B, the bolt and nut being indicated generally at 9. The upper end of the bracket is laterally offset as at l0, this being horizontally disposed and serving to accommodate the lateralhorizontal foot II on the Another phase of the invention has to do with a suitable supporting bracket structure which 25 2 lower end of .the upper bracket l2. The two brackets are bolted together, as at II, the bolt passing through the abutting lateral foot members Ill and II. The upper bracket terminates at its upper end in a so-called split part-spherical socket I l, the parts being bound together by a clamping bolt II. A ball jointing element It fits in the socket and is integrally attached to the customarily shaped casing I! of the headlight assembly.

'The-anti-glare lens unit is denoted by the numeral l8 and, as before indicated, is preferably a one-piece device constructed of transparent glass or equivalent material. It is characterized by a flat. disc-like inner lens I! and a companion outwardly spaced concave-convex outer lens 20. The concave surface of the latter lens is provided with a multiplicity of light-diffusing projections 2| forming a so-called honey-comb. and said projections being preferably prismatic in form. The two lenses are connected by an endless or annular marginal rim 2!, thus forming a receptacle for the water filter medium 23. The

rim :2 is confined in and surrounded by a metal or equivalent assembling and retaining frame 24, this being of general channel shaped cross-sectional form and having its inner flange 25 interlocked with a flange on the open side of the shell or casing H, as shown in the drawing. A somewhat wider flange 2|, on the outer peripheral edge, engages the adjacent marginal edge portion of the outer lens 2l.- The part 24 is nontransparent to prevent light rays from passing through the parts of the lens unit covered thereby. The reiiector is denoted at 2! and the conventional lamp bulb at 28. The outer marginal edge of the reflector contacts the inner lens I! at about the region or area indicated.

It is believed that a headlight equipped with a double lens chamber or receptacle with water or an equivalent liquid' between the two lenses will function to diminish objectionable headlight glare.

Also, as before indicated, a special supporting bracket, forming the supporting means 5, contributes to a proper support of the headlight from the car or automobile to thus enhance its safety features.

Although it is perhaps of no patentable moment, I desire to set forth here the fact that in certain seasons, and frigid areas it may be necessary, in actual practice, to introduce clear alcohol into the body of water this to function as an anti-freeze agent.

It is thought that persons skilled in the art 1.
